It's interesting how people see hope differently.
False hope to me is when someone is intentionally lying to you making promises that they can't keep or knowingly letting someone believe in something that's false. Sometimes people simply fail to consider whether they can keep a promise or not, which I also find irresponsible.
Yes, some people do prefer this over no hope at all. They even deliberately gravitate towards those who they know are irresponsible with promises because false hope is guaranteed. But others would rather brutal honesty so they can move forward or in a different (more fruitful) direction.
